Directed by Jason Osder, "Let the Fire Burn" chronicles the events that surrounded the 1985 encounter between the radical black organization MOVE and the Philadelphia authorities.

Other films in the festival, which continues through Oct. 13, are the Sundance and Toronto Film Festival winner "The Square," which focuses in Cairo's Tahrir Square; "The Other Shore," which chronicles Diana Nyad's history-making efforts to swim from Cuba to Florida; and Mahdi Fleifel's "A World Not Ours," about Palestinian refugees in a Lebanese refugee camp.

"ArcLight Cinemas is about the celebration of film, and we are ecstatic that the festival continues to grow and thrive in a city that has long been the epicenter for incredible storytelling," said Gretchen McCourt, executive vice president, cinema programming.

"The submissions showcased at this year's festival are outstanding contributions to the ever-growing world of documentary film," McCourt said. "We couldn't be more pleased to support such a talented group of filmmakers."

The top documentaries in the festival will be honored at a reception at the ArcLight on Oct. 13. Festival goers will be able to pick an Audience Favorite, while a jury winner will receive a $10,000 prize.
